- SCREEN Application led- April 3 trisv a further object to provide. a screenr frame having sides. each formed of a pair ot' plates between which the screen Clampett.y and provide clamping means for sail screen which will irmly secure .the

screen and stretch the saine when said frame is assembled and which will,v moreover protert the screenffrom tear-ing'.

It is a. more specific object of the inven-l tion to provide a screen frame having sides composed of apair ot preferably metallic plates, between wliicli the .screen is secured,

one of said plates havingwa longitudinal groove-therein whigcliis adapted to receive said screen, and a rod adapted to be seated in saidgroove to clamp thescreen therein.

A stillli further object is to provide elongated lips at the inner sides of said frame between which the screen is also clamped.

These and other objects of the invention will be apparent from the description made in connection with the accompanying drawings, wherein like notations refer to similar parts throughout the several views, and in which Fig. l is a fragmentary front elevation of the preferred form of the invention;

Fig. 2 is a horizontal cross section of one of the sides of the frame taken on the line 2 2 of Fig. l; and

Fig. 3 is a similar crossl section of the modified form of the invention.

The screen frame comprises a plurality of sides which are welded together, or otherwise secured, at their ends. v Each of said sides is formed of a pair of plates designated asv entireties by the'letters A and B respectively, between which the screen C is clamped7 said plates being secured together by bolts Ll or any other suitable means. The plate A has a relatively large longitudinal channel portion 5 forming the body of the frame7 a longitudinal groove 6) slightly greater than a semi-circle in cross section and extending parallel with the channel portion 5, the flat portion 7, between channel 5 and groove 6 and the flat inner side portion or lip 8. Plate B comprises the flat body portion 9 having the upturned side portion l0 adapted to snugly iit within the 1.9.245- Srl Np,- 29,387:

outer side ofthe channel portion 5 to for-n1 the closed outer edge of the frame.

rvShe edge olfv the screen' extends` between the` pirates A andi B. and is clamped within the. groove.V G by. means of a rod 11 adapted tobe tightly seated therein. The portions 7 and 8- of plate VA extend in the same plane and co-,operate with the bodyl portionl 9 of plate B to further clamp the screen, portions 8 and 9 of saidplate forming longi-V tudinal lips at the inside edgesof the.. frame.

In the modified form shown in- Fig.i 3, the plate A is in every respect,A simi-lar to the plate A of the preferred forni, except that the outside edgeV of the ohannel por-J tion 5- is inturned to receive the semicylindrical inturned outer edge. 10i1 of the plate,

the -edge'of` the frame permittingthe frame to be slidably seatedon abeadg or strip.

'mounted' on thesid'es of; the wigndowvf.,

It will be Seen thaty in Securingth screen Within the frame the screen is stretched when the rod l1 is forced into the groove 6. The plates A and B are-preferably con st ructed of pressed sheet metal, thereby providing sufficient resiliency in the groove 6 to permit rod l1 to be inserted and firmly secured therein.

From the .above description, it Will be seen that applicant has provided a simple buthighly efficient decorative screen frame capable of being manufactured at little eX penseand adapted to securely clamp the screen therein without injuring or tearing the same. Y

Extensive actual usage of the device has proven the same to be highly successful for the purposes intended. y

It will, of course, be understood that various changes may be made in the form, details, proportions and arrangement of parts without departing from the scope of this invention.

lWhat is claimed is: Y

l. A lscreen comprising a frame member having an open groove formed therein the side walls of said groove adjacent its edges being resilient, and having' relatively Wide flat supporting surfaces on each side of said groove, a screenfabric extending across said flat surfaces and into said groove, a rod held in said groove by saidresilient edges to secure said screen under tension to said frame membera second frame member co- This construction` forms a groeve l2 inextensive with said first member and having flat surfaces opposite the flat surfaces on said first member, and fasteners extending through said members and clamping said screen fabric between'said flat surfaces.

2. A screen comprising a frame member formed to provide a reinforced edge, an open groove with side walls having resilient edges slightly overlianging said groove, and a fiat surface between said edge andv groove, a screen fabric extending into said groove and across said flat surfacev a rod held insaid channel by said resilient edges to secure said screen under tension to said frame member,

and a second frame'Y member including an edge reinforcement cooperating with the reinforcement on said first named member to constitute a reinforced frame and a flat surface designed to lie opposite the flat surface on said first named member and fastening elements securing said members together with the screenfabric clamped between said flat surfaces.

3. Avscreen comprising a frame member formed to rovide a reinforced edge, an open groove, a at surface outward of said groove between saidv edge and said groove, and

a flat surface inward from said groove and disposed insubstantially the same plane assaid first mentioned flat surface, a vscreen fabric extending into said groove and across said Vfiat surfaces, a rod held in said groove to clamp said screen fabric between the same' and said groove, and a second frame member including a reinforced edge co-operating with the reinforced edge of said first mentioned frame member, and a flat surface designed to oppose the flat surfaces of said first mentioned member to clamp portions of said screen fabric therebetween and fastening elements securing said members togethern 4. A screen comprising a frame member formed to provide a reinforced edge, an open groove with side walls having resilient edges slightly overliangingsaid groove, a flat surface between said edge and one side of said groove, and a flat surface between the other side of said groove `and the other edge of said frame member, a screen fabric extend-v ing into said groove and across said flat surfaces, a rod heldin said ygroove by'said resilient edges to secure said screen underr All tension to saidframe member, and a second frame member including an edge reinforcement co-operating with the reinforcement on said first named member to constitute a reinforced frame and a Hat surface designed to lie opposite the flat surfaces on said first named member and fastening elements securing saidmembers together/with the screen fabric clamped between the opposing' fiat surfaces.

In testimony whereof I aflix my signature.
